|
Initialize a Task, supplying a thread manager and a message queue. If the user doesn't supply a ACE_Message_Queue pointer then we'll allocate one dynamically. Otherwise, we'll use the one passed as a parameter. |
|
Destructor.
|
|
|
|
Tests whether we can enqueue a message without blocking.
|
|
Dump the state of an object.
Reimplemented in ACE_Stream_Head<>, ACE_Stream_Tail<>, ACE_Thru_Task<>, ACE_Svc_Handler<, >, ACE_Buffered_Svc_Handler<, >, and ACE_Svc_Handler< ACE_PEER_STREAM_2, ACE_SYNCH_USE >. Referenced by ACE_Stream<>::dump(). |
|
Flush the task's queue, i.e., free all of the enqueued message blocks and unblocks any threads waiting on the queue. Note that if this conflicts with the C++ iostream function, just rewrite the iostream function as ::. |
|
Extract the first message from the queue (blocking). Note that timeout uses <{absolute}> time rather than <{relative}> time. Returns number of items in queue if the call succeeds or -1 otherwise. |
|
Return the Task's Module if there is one, else returns 0.
|
|
Sets the message queue associated with this task.
|
|
Gets the message queue associated with this task.
|
|
Return the name of the enclosing Module if there's one associated with the Task, else returns 0. Referenced by ACE_Stream<>::dump(). |
|
Set next Task pointer.
|
|
Get next Task pointer.
Referenced by ACE_Stream<>::dump(), and ACE_Stream<>::push_module(). |
|
|
|
Transfer message to the adjacent ACE_Task in a ACE_Stream. Note that timeout uses <{absolute}> time rather than <{relative}> time. |
|
Insert message into the message queue. Note that timeout uses <{absolute}> time rather than <{relative}> time. |
|
Turn the message around, sending it in the opposite direction in the stream. To do this, the message is put onto the task next in the stream after this task's sibling.
|
|
Return the Task's sibling if there's one associated with the Task's Module, else returns 0. Referenced by ACE_Task< ACE_SYNCH_USE >::reply(). |
|
Return a message to the queue. Note that timeout uses <{absolute}> time rather than <{relative}> time. |
|
Manipulate watermarks.
|
|
|
|
|
|
Declare the dynamic allocation hooks.
Reimplemented in ACE_Stream_Head<>, ACE_Stream_Tail<>, and ACE_Thru_Task<>. |
|
1 if should delete Message_Queue, 0 otherwise.
|
|
Back-pointer to the enclosing module.
|
|
Queue of messages on the ACE_Task..
|
|
Pointer to adjacent ACE_Task.
